In this section, you will learn how the heart works and the important role played by the coronary arteries, valves and electrical system of the heart. You also will receive some basic information about irregular heartbeats, coronary artery disease, angina (chest pain) and heart attacks.
The heart is a muscle about the size of an adult male fist. Its job is to pump blood to all parts of the body.
The heart’s pumping action is controlled by an electrical system that sends out impulses, or signals.
Angina is not a disease but is a symptom of heart trouble. It is a pain or discomfort that happens when part of the heart muscle is not getting enough blood. It is usually brief, lasting just a few minutes.
A heart attack occurs when a blood vessel (coronary artery) that feeds the heart becomes blocked and cuts off blood flow to the heart muscle (myocardium).
